DRILLING-MACHINE.

Application filed April 19, 1919. Serial No. 291,245.

To all whom. it may concern Be it known that I, OTTO D. NORMAN, a citizen of the United States, residing at Spencer, in the county of Roane and State of West Virginia, have invented certain new and useful Improvements in Drilling-Machines, of which the following is a specification.

This invention relates to drilling machines, such as used in drilling wells, and an object of the invention is to provide a well drilling machine structure wherein an internal combustion engine of any approved type is employed, both for tractive power and for drilling power, of the machine, and further to provide a novel form of transmission mechanism for transmitting the power .from the internal combustion engine to the drilling mechanism operating pulley and also to the traction wheel operating structure, the latter being normally idle from connection, with the prime mover, and including a sprocket which is mounted upon the shaft that carries the pulley for operating the drilling mechanism, and to provide a pair of removable pins adapted to extend through the sprocket and into the hub of a pulley for operatively connecting the sprocket to the pulley to ope-rate the speed change gears and transmit power to the traction wheels of the device.

A further object of the invention is to provide in a well drilling machine utilizing an internal combustion engine as power, means whereby the magneto operating shaft of the internal combustion engine may be connected direct to the blower utilized in the well drilling machine foroperating the blower by operation of the engine.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings:

Fig. 11 is a detail section illustrating a detachable connection of. clutch operating levers used in the drilling machine.

Referring more particularly to the drawings, wherein like characters indicate like and corresponding parts throughout the several views, A indicates the supporting frame as an entirety of the drilling machine which frame carries the usual drilling mechanism indicated at B and including the usual form of tower C.

An internal combustion engine 1 of any approved type is supported by the chassis or supporting frame A of the well drilling machine and the power shaft 2 thereof has a beveled pinion3 mounted upon its outer end, which beveled pinion meshes with a beveled gear 4.. The beveled gear 4 is mounted upon a shaft 5 which extends transversely of the frame A and has a pulley 6 keyed thereon. The pulley 6 is connected-to the operating mechanism '13 of the well drilling structure by a belt 7 for operating the well drilling mechanism B by operation of the internal combustion engine 1. The frame A carries the usual front axle 10 upon which are mounted the front wheels 11 and it also carries the rear axle 12 upon which the rear traction wheels 13 of the well drilling machine are mounted. These tract-ion wheels. 13 have crown gears 14 carried thereby which mesh with pinions 15. The pinions 15 are mounted upon a shaft 16 which extends transversely of the frame A and which carries the gears 17 and 18 which coact with gears 19 and 20 carried by a shaft 21 to provide the speed change gears for changing the speed of travel of the Well drilling machine. The shaft 21 is positioned above the shaft 16 and it has a sprocket 22 mounted thereon about which a sprocket chain 23 travels. The sprocket chain 23 also travels so that it may be conveniently reached and operated by an operator standing upon the about a sprocket 24 which is'loosely mounted upon the shaft 5, permitting the shaft to rotate independently of rotation of the 5 sprocket 24 during the fiperation of the well drilling mechanism. wever, when it is desired to move the Well drill from one place to another, the belt 7 is thrown off the pulley 6 and a plurality of pins or bolts 25 are inserted through the openings 26 formed in the sprocket 24 and into openings 27 formed in the hub 28 of the pulley 6, thus operatively connecting the sprocket 24 with the shaft 5, to rotate the said sprocket and consequently 1 the shaft 21 and shaft 16 by the operation of the internal combustion engine 1.

A dual control for the fuel supply or gas to the engine 1 is provided, it including a lever 30 positioned at the rear end of the 2 machine, and a second lever 31 which is pivotally mounted as shown at 32 at the forward end of the machine and is connected by means of a rod 33 to the carbureter of the engine for controlling the supply of fuel to the latter. Suitable quadrants are provided for maintaining the levers and 31 in adjusted positions. A clutch control lever 34 is also positioned at the forward end of the machine, being connected by means of. a. 30 shaft 35 and suitable links as shown at 36 a with the clutch operating arm 37. The

clutch operating arm 37 also has a bar or rod 38 connected thereto which is in turn adjustably connected as shown at 39 to the 35 brake lever 40. The rod or lever 38' extends to the rear end of the machine, where a hand lever 41 is provided for operating it. When drilling a Well with the machine, the brake lever which is pivotally connected tothe 40 frame A is disconnected, to permit operation of the clutch independenly of the brake.

The magneto drivingshaft 43 of the internal combustion'engine 1 has apulley 44 45 mounted thereon about which a belt 45 travels. This belt 45 also travels about the operating pulley 46 of the blower '47 which is used to provide a draft for forge (not shown in the drawings) used in heating bits, 50 etc.

of speed ahead or reverse for controlling the operation of the drilling mechanism B while the speed change gears 17, 18, 19 and 20 form a second set of speed change gears for controlling the drive of the traction wheels 13. A lever 48 is provided, for controlling the usual speed change gears of the engine, and this lever is pivotally supported by a bearing member 49, which bearing member is pivotally connected to a pivotal support or are 50. The hand grip5l of the lever 48 is positioned at the rear end of the machine platform 52. The levers 30 and 41 are also positioned for convenient reach and operation from the platform 52.

When it is desired to ope'rate the well drilling mechanism B by the engine 1, the belt 7 is passed about the pulley 6 and about the operating pulley 53, of the mechanism B, after WlllClltllG lever 48 may be shifted to provide the proper speed of rotation of the shaft 2 by operation of the engine 1 and the power is transmitted from the shaft 2 to the shaft 5, and consequently to the pulley 6.

When it is desired to transport or move the well drilling machine, the belt 7 is slipped off the pulley 6 and the pins 25 are inserted through the openings 26 into the openings 27 for connecting the sprocket 24 operatively with the shaft 5. The power is transmitted from the shaft 5 through the sprocket 24, chain 23, to the shaft 21, where the tractive speed ofithe well drilling .machine may be regulated by the shifting of either of the gears 19 or 20 into the respective gears 17 and 18, thus transmitting the I motion to the shaft 16 and from this shaft to the traction wheels 13, through the medium of the pinion 15 and the gears 14.

In Figs. 9 and 10 of the drawings, the shaft 5 hasa brake pulley of wheel 41 mounted thereon upon the opposite side of the beveled gear 4 from the pulley 6 and a friction brake band 40 extends about the periphery of said brake pulley or wheel, having one end connected to a suitable support 42 and the other end connected to the wrist or crank 43. The shaft 44* upon which the crank 43 is formed' is supported by suitable bearings 45 and is extended upwardly as clearly shown in Figs. 9 and 10 of the drawings, being connected to a rod 46 which extends rearwardly along the chassis of the drilling machine and has its rear end connected to the rod 47 which extends rearwardly across the rear end of the chassis and has a hand lever 41 connected thereto for operating the friction brake band 40. This rod 47 also has the longitudinally extending bar 38" connected thereto by means of which the clutch mechanism of the power plant is operated, and thus through the medium of this mechanism. the brake band 4O will be moved into gripping engagement with the brake wheel 41* simultaneously with the operation of the clutch mechanism of the power plant.

The clutch operating lever 37' has a control lever 34* connected thereto through the medium of a series of links 36 as disclosed and specified in the preferred form of the invention which control lever extends to the rear. end of the drilling machine. Howis desirable to have this control lever 34:

- disconnected from the clutch lever 37 and also have the brake operating lever or rod 46 disconnected from the clutch operating rod or bar 38 and to permit such independent operation of the clutch with respect to the brake, the bar or rod 46 is detachably connected to the upright portion of the shaft 44; by means of a bolt 4:8 as clearly shown in Fig. 11 of the drawings. The bolt 4:8 has its free or threaded end 4:9 reduced to provide a shoulder, against which a washer 50 abuts and is clamped, by means of a nut 51 thus pivotally and detachably connecting the rods .46 to the shaft 44*. The links 36 the lever 37 by a bolt 4.8 identical with the construction illustrated in Fig. 11 to permit disconnection between the levers 34 and 37 during the traction of the drilling machine if it is so desired.

By providing the brake pulley or drum 4:1 upon the shaft 5 vand also by providing the detachable'connection between the bar 46* and the shaft 44? this brake mechanism may be rendered mopenative or inactive during the travel of the drilling machine, without necessitating the detaching of the brake mechanism as is necessary in the preferred form illustrated in Figs. 2 and 3 of the drawings.

Changes in details may be made without geparting from the spirit of this invention,
